Step 2: text step 1 gained being had to matrix of areas reads, extracts area information, inquires corresponding fabric fill directional information by zone number in storehouse; Through fabric information initializing, carry out fabric Fast Filling;
Step 3: read borderline documents text, obtains matrix of edge, utilizes composite formula P=aF+ (1-a) S in imaging importing process to process clothes edge, wherein a is corresponding pixel points blackness, design sketch after to be fabric figure, P be process that B is style figure, F.
Described information storage process is: adopting the method identification clothes region that region increases, is designated color by clothes regional processing, and to the region number consecutively selected, numbers, pixel corresponding for this region mark stored in matrix of areas for this reason; The direction of selected zone fabric is defined, after the zone number in this region is associated with the fabric orientation angle in this region, preserves into database; While region increases, calculate the gray-scale value g (i, j) at image of clothing edge pixel point position (i, j) place, then calculate blackness a=g (i, j)/255 of this pixel; Finally the data write text in two matrixes is preserved.
Described fabric Fast Filling process is:
Step 1: to the reading of text having matrix of areas, obtain matrix of areas;
Step 2: read the identical matrix of areas content of numbering, obtain a certain clothes area information, inquires corresponding fabric by zone number and fills directional information in storehouse;
Step 3: reading area matrix, replaced by corresponding pixel in fabric figure good for the pixel initialization of identical numbering corresponding in matrix of areas correspondence in style image, now a certain region fabric of clothes has been filled;
Step 4: repeat aforesaid operations, realize the Fast Filling of image of clothing fabric.
The invention has the beneficial effects as follows, for the demand that clothes two-dimensional virtual is shown, propose a kind of garment material method for quickly filling based on matrix of edge, reduce the man-machine interactively in garment material filling, optimize the filling process of garment material, to some extent solve garment material in garment virtual display and fill the time-consuming problem of difficulty.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of a kind of garment material method for quickly filling based on matrix of edge of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

Concrete enforcement according to the following steps:
Step 1: image processor extracts the region of image of clothing and marginal information;
Step 2: according to step 1 information extraction, adopts region growing algorithm and zone number labelling method defined range matrix A [width, height], and wherein width is the width of agreement image of clothing, and height is the height of agreement image of clothing;
Step 3: adopt region growing algorithm and threshold restriction method definition matrix of edge E [width, height], wherein width is the width of agreement image of clothing, and height is the height of agreement image of clothing;
Step 4: the gray-scale value g (i, j) establishing a certain pixel (i, j) place in clothes region, now blackness a=g (i, j)/255 of this pixel, chooses arbitrary pixel (x, y), calculates its blackness;
Step 5: the blackness value of pixel selected by step 4 is judged, if a > 0.15, represents that this pixel belongs to matrix of areas, using pixel pixel (x, y) as Seed Points; And the pixel of this Seed Points pixel (x, y) is set to yellow, and 1 is numbered to this Seed Points region, be 1 by the Seed Points coordinate element assignment that A [x, y] is corresponding in matrix of areas; Successively respectively x++, x--are carried out to the transverse and longitudinal coordinate of Seed Points pixel (x, y), y++, y--, obtain four new pixel pixel (x+1, y), pixel (x-1, y), pixel (x, y+1), pixel (x, y-1), respectively these four pixel blackness are judged, to the point of a > 0.15 be met as new Seed Points, continue to repeat aforesaid operations, complete the selection of an area information;
Step 6: according to the determination methods of step 4, if a≤0.15, then represents that selected pixel color is not yellow, belongs to matrix of edge; According to the method for step 5, complete the selection to whole matrix of edge information;
Step 7: direction filled by the fabric of the mode defined range of manually ruling, and associated by definition orientation angle corresponding for region with zone number;
